I can't help you with your patch, I looks rather compicated at the first 
sight. But, my question is: do you really want to do these calculations 
in pd? I'm sure, there are some more appropriate solutions. E.g. in 
Matlab (you can use Octave, as well), my solution is:

x=wavread('filename');
y=x./max(max(abs(x))); % find the max. peak in any channel
wavwrite(y, FS, 'newfilename'); % FS=sampling rate

br, Peter
